Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 13FR020 is determined by the following critical parameters:

• Resistance value: 20 mOhms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Metal Element
• Features: Current Sense, Non-Inductive
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 275°C
• Package: Axial
• Physical dimensions: 0.205" Dia × 0.571" L

The substitute part 13FR020E matches all electrical and mechanical specifications. The primary difference is packaging configuration (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both 13FR020 and 13FR020E are electrically and mechanically identical. Selection between these part numbers should be based on:

• RoHS compliance requirements: The 13FR020E meets ROHS3 compliance, while the 13FR020 does not. Applications subject to RoHS regulations must use 13FR020E.
• Packaging requirements: The 13FR020E is supplied in Bulk packaging, while 13FR020 uses standard packaging. Procurement specifications may dictate packaging preference.
• Inventory availability: 13FR020E has higher stock levels (13,811 pcs) compared to 13FR020 (1,101 pcs).

Both parts carry Active product status and are manufactured by Ohmite under the Series 10 designation.

Frequently Asked Questions (FAQ)

Q: Can 13FR020E be used as a direct replacement for 13FR020?

A: Yes. The parts are electrically and mechanically identical. All critical parameters—resistance, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions—are identical. The primary differences are packaging format and RoHS compliance status.

Q: What is the difference between the two part numbers?

A: The 13FR020E is the Bulk-packaged variant with ROHS3 compliance. The 13FR020 uses standard packaging and is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Which part should I specify for new designs?

A: Specify 13FR020E for new designs if RoHS compliance is required. Both parts are Active and suitable for production use.

Q: Are there any thermal or electrical performance differences?

A: No. Both parts have identical temperature coefficients (±50ppm/°C), operating temperature ranges (-55°C to 275°C), and all electrical characteristics.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts use identical Axial package dimensions (0.205" Dia × 0.571" L) and have two terminations. PCB footprints and mounting requirements are identical.
